摘　　要：以枳砧晚熟脐橙幼树为试验材料,研究了微喷灌和滴灌对变质页岩母质发育的黏重黄壤果园中脐橙幼树生长及产量的影响。结果表明,微喷灌和滴灌都能有效地促进脐橙的生长和增加其产量,与对照相比,滴灌和微喷灌单果重较对照分别增加9.57%和38.83%,单株产量分别增加90.9%和36.4%;微喷灌和滴灌均能有效地增加新梢的生长量、树体的树高、干径、冠幅;对土壤黏度较大的黄壤果园,微喷灌节水灌溉方式的技术经济效果较滴灌好。Taking naval orange young tree on yellow sticky clay of orchard mountain as material of experiments, the influence of the spray irrigation and the drip irrigation to the growth and the yield of navel orange young tree has been compared. The result showed that the spray irrigation and the drip irrigation all can promote navel orange young tree growth and increase plant yield effectively. Compared with the control drip irrigation and micro-spray irrigation fruit weight than the control increased by 9.57% and 38.83% , the yield increased by 90.0% and 36.4% , significatly increased the shoot growth and tree height, tree trunk diameter, tree-crown diameter; on the mountainous orchard of yellow sticky clay, the spray irrigation is an economical and effective irrigation method which is better than drip irrigation.
